UHRF1 regulates the localization of TopoIIα at PCH.
a, SFB-tagged WT and point mutants of UHRF1 were electroporated into MEF cells, and their localizations were visualized by staining with anti-FLAG antibody. b, SFB-tagged WT and deletion mutants of TopoIIα were electroporated into MEF cells, and their localizations were visualized by staining with anti-FLAG antibody. c, the localizations of endogenous TopoIIα in the different ES cells indicated were visualized by staining with anti-TopoIIα antibody. Twenty-five cells were quantified for each experiment in a and b, and 100 cells were quantified for each experiment in c. Error bars represent the mean ± S.D. KO, knock-out.
